ELECTROCHEMICAL NOISE CORROSION MONITORING IN HYDROCARBON PIPELINES - FIELD EXPERIENCE

摘要

This paper describes the field investigation performed to characterize the corrosion behavior in a fully- inhibited water-containing hydrocarbon transport line. Modem multi-technique electrochemical monitoring instrumentation incorporating Electrochemical Noise and Linear Polarization techniques was employed. The data obtained were analyzed on-line and correlated with short-term upsets in process operation enabling a troubleshooting exercise to be undertaken, and ultimately validating the effectiveness of the existing chemical treatment program.
